*3 Claims.

My invention relates to circular knittingmachines and moreparticularlytomeans. for protecting the knitted productirom oil andthe-like whichnecessarily accumulates on both the-moving and stationarymarts.otithe'machine. JSuch attachments have heretofore been proposed forprotecting the product of a'circular knitting machine from grease andoil, but these are not well adapted for use in the improved machines nowcommonly employed for knitting hose. It is therefore the object of myinvention to provide attachments that are particularly applicable tocircular knitting machines having take-up devices for drawing theknitted product mechanically into a container, and especially those inwhich the winding rollers of the takeup mechanism rotate intermittentlyon their horizontal axles and continuously about a vertical axis.

In the drawings accompanying and forming part of this specification, Ihave illustrated my invention as applied to one well-known type ofcircular knitting machines, but it is to be understood that I do notlimit myself thereto.

Figure 1 is a perspective view of those parts of a circular knittingmachine that constitute my invention, various other portions of themachine being indicated in dotted lines.

Fig. 2 is an elevation showing my invention on a larger scale, certainportions being in section.

Fig. 3 is an elevation of a product supporting member and oil guard.

Fig. 4 is an elevation partly in section of a portion of the containerand the winding rollers whereby the product is drawn into the container.

Figs. 5 and 6 are plan views of oil guards which prevent the productfrom coming into contact with the inner surface of the stationary camwhile it is being removed from the container.

In the particular drawings selected for more fully disclosing myinvention and the principles underlying the same, said drawings beingmerely illustrative and by no means restrictive, I0 is a circularknitting machine having a bottom needle cylinder ll enclosing a sinkersleeve l2 within the lower portion of which is disposed the upperportion of a tube l3, said tube terminating in an inverted truncatedcone HI,- the members [3 and I4 comprising an inverted funnel-likemember, which is shown in the present instance as supported by thebracket l5.

Preferably, the rim of the substantially coneshaped member I4 isup-turned 'to form an annular basin for receiving the oil which flowsaround the outer surface of the said funnel-like TT ING MACHlNE h r ks,Westwood, Mass.

1947, s rial-No. "1 ,696 (c 6. 1 member. The rim .I6 of the. cone may beprovided with an overflow lip l1, and; in such case,

.atrough [8 may be placed :beneath saidlip for conducting the overflowinto a receptacle, i9.

' .Itis desirable that; the :substantially. coneshaped member I l bedisposed immediately above the product container 20 and spread outwardlyabove the open end of the latter.

Mounted on the top of the container is a winding roller bracket 2| onwhich are mounted for rotation about their axles 22, 22, the take-uprollers 23, 23, whereby the knitted product indicated at 24 is drawnfrom the bottom needle cylinder into the container.

By means of mechanism well understood and therefore unnecessary to beshown, the take-up rollers and their support revolve around a verticalaxis continuously. By means of other mechanism, not shown, the rotationof the rollers 23 about their axles is intermittent, such mechanismbeing controlled by the stationary cam 25.

As oil invariably accumulates on the inner surface of said cam, meansare provided to protect the product while being removed from thecontainer from the oil which collects on the inner periphery of saidcam. One form of such protecting guard is shown at 26, being in thisinstance substantially segmental in shape and provided with a flange 21depending vertically from its straight edge, such flange being slightlyspaced from the inner surface of the cam. The arrangement is such thatwhen the operator draws the finished stocking or other knitted productfrom the container, the stocking passes over the guard and does not takeup any of the oil or rease accumulated on the inner surface of said cam.

In Fig. 4, I have shown another form of winding roller bracket to whichare secured the flanged guard above described and a segmental guard 28secured to said bracket approximately diametrically opposite the guard26. In the present instance, the guards are shown attached to thebracket by the screws 26', 28', respectively.

The quality drum 29 is actuated by a chain 30 co-operating with suitablesprockets, an arrangement which requires substantial and continuouslubrication. To conveniently support the finished knitted product at apoint close to the container and protect the same from oil, I haveprovided a hook 3! suitably attached to the machine and passing througha slot in a vertical plate 32, said plate having a flange 33 on one ofits vertical sides, said flange being interposed between the 55 sprocketand the product.

Having thus described illustrative embodiments of my invention without,however, limiting the same thereto, what I claim and desire to secure byLetters Patent is:

1. In a circular knitting machine having a needle cylinder and acontainer into which the knitted product is drawn mechanically, meansfor protecting such product from oil, said means comprising an elongatedtube the upper portion of which is disposed within said cylinder andadapted to receive such product and direct it to said container, and aninverted substantiallyconically shaped member secured to said tube ofsaid prising a member having a shank and a conical portion, a portion ofthe shank of said memberbeing within said cylinder and the conicalportion thereof being intermediate said cylinder andsaid container, therim of said conical portion being up-turned to form an annularbasin forreceiving the oil flowing along the outer surfaces of said tube and saidmember, said member being adapted to receive such product and direct itto said container, a receptacle gbelow said conical 7 portion and meansfor directing theoil over flowing said basin to said receptacle. 7PHHIIP A.
